Abstract

In different laser applications the laser induced plasma governs the process of energy coupling into the workpiece particularly in laser welding. Using a cw-0O2-laser, the plasma shows temporal and spatial fluctuations with typical frequencies. During these fluctuations the Plasma disappears completely for approximately 0.2 ms. Amongst other things it is demonstrated that there is a strong correlation between the plasma fluctuations and the dynamics of the molten metal.
